虚拟语气在一些特殊词中的使用或含蓄条件句
1.wish后的宾语从句。
与现在愿望不一致,用主语十过去时,例如:
I wi。hIwere you.
与过去愿望不一致,用主语+had+过去分词,例如:Iwish I had visited the White House whenI was in the States与将来愿望不一致,用主语+would (could)+原形。
2.It's time句型:当lt's tine后用that从句时应该为主i吾+should+动词原形或主语十过去时,例如:It,s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感叹句相当于“How I wish+宾语从句”。
(l)If only he could come.他要能来就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather,as if(though)引导的从句也需使用虚拟语气,表示过去的情况用过去完成时,表示现在与将来的情况用过去时,例如:
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句,而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有:
(1)介词或介词短语。如but for,but that,without,in case of, under more favorable condition等。
(2)连词。如so that, unless, in case, supposing,lest, provided(倘若……),for fear that(唯恐),in orderthat, on condition that, if only(要是……就好了)等。
注意:lest, for fear that和in case引起的从句中谓语动词多用should+动词原形,但也可以不用虚拟语气,而用动词的陈述语气形式。例如:The foreign teacher spokeslowly in case we misunderstood him这位外籍教师说得很慢以免我们误解。
(3)通过上下文及内在含义,句中往往有but,otherwise, unfortunately等类似转折词。
without, but. but for, otherwise引起的短语或句子常暗含着含蓄条件。例如:
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!

一、that 从句
1、主语从句
(1)that从句作主语时,常用it作形式主语,常见的句型有:
It+be+形容词(obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句
It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.)+that从句
It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句
(2)that可以省略,但that从句位于句首时,that不能省略。
2、宾语从句
(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词之后,如think, make, consider等,可以用it作形式宾语。
(2)That从句一般不能充当介词宾语,偶尔可作except, in 的宾语。
3、表语从句(that不可省略)
4、同位语从句
连词that引导同位语从句时,应在某些抽象名词之后,如:fact, hope, desire, thought, suggestion, idea, news, problem, possibility等,对前面的名词起补充说明的作用,that在从句中不担当任何成分,不能省略。
二、whether/if从句
1、在表语从句和同位语从句中只能用whether不能用if;当主语从句放于句首时,只能用whether不用if;当it作形式主语,主语从句放在句末时用whether或if均可;discuss后引导宾语从句时,必须用whether。
2、在宾语从句中:
(1)及物动词后:whether从句中不能有否定式,宾语从句为否定句时用if;if不能与or not连用,但可以用whether or not;whether后可以加不定式。
(2)介词后:只能用whether,不用if。
三、特殊疑问词引导的从句
1、主语从句:特殊疑问词引导主语从句时,常用it作形式主语。
2、宾语从句
(1)常见的能接特殊疑问词引导的宾语从句的动词有see, tell, ask, answer, know, decide, find out, imagine, suggest, doubt, wonder, show, discuss, understand, inform, advise等。
(2)作介词宾语。
3、同位语从句、表语从句
四、名词性关系从句
What=the thing(s)
which/that
whoever=anyone who
whichever=anyone/anything that
whatever=anything that
where=the place where
when=the time when
五、名词性从句的几个难点
(一)that不可省略的情况
1、主语从句,that从句置于句首时;
2、当一个句子有两个或多个并列的宾语从句时,引导第二和以后几个从句的that不可省略;
3、由it作形式宾语时,that引导的宾语从句中,that不可以省略。
(二)wh-ever与no matter wh-的用法区别
Wh-ever既可引导名词性从句,又可引导让步状语从句;而no matter wh-只能引导让步状语从句。
(三)as if/though, because, why可以引导表语从句
注意:because引导的表语从句,主语不能是reason或cause,而且since,as不能引导表语从句。
(四)that引导的同位语从句与关系代词that引导的定语从句的区别
That引导的同位语从句成分是完整的,that在从句中不担当任何成分;that引导的定语从句成分是残缺的,that在从句中充当主语、宾语或表语。
